Abstract
A non-transitory computer-readable medium storing a computer program capable of providing an easy-to-interpret image. A computer acquires, according to a computer program, a signal data set by a first inspection wave emitted in a direction inclined at a first angle with respect to a longitudinal axis direction of an imaging core used in a catheter. Then, the computer constructs an image obtained by using a direction inclined at a second angle different from the first angle with respect to the longitudinal axis direction of the imaging core as an observation target, based on the acquired signal data set.
Claims20
A non-transitory computer-readable medium storing a computer program that causes a computer to execute a process comprising:
- acquiring a signal data set by a first inspection wave emitted in a direction inclined at a first angle with respect to a direction on a proximal end side on a longitudinal axis of a shaft of an imaging core of a catheter;
- and
- constructing an image obtained by using a direction inclined at a second angle with respect to a direction on a distal end side on the longitudinal axis of the shaft of the imaging core of the catheter, and wherein the second angle is different from the first angle with respect to the longitudinal axis as an observation target, based on the acquired signal data set.
An image processing method executed by a computer, the method comprising:
- acquiring a signal data set by a first inspection wave emitted in a direction inclined at a first angle with respect to a direction on a proximal end side on a longitudinal axis of a shaft of an imaging core of a catheter;
- and
- constructing an image obtained by using a direction inclined at a second angle with respect to a direction on a distal end side on the longitudinal axis of the shaft of the imaging core of the catheter, and wherein the second angle is different from the first angle with respect to the longitudinal axis as an observation target, based on the acquired signal data set.
